Speaking as one of the people involved with this, well, we all like Zecora. And putting someone we liked on the side of the Black Lanterns seemed like a way to get across just how much trouble the ponies were in.

I know that, but considering the fact that it’s the mane six who were born and raised in Equestria, it makes sense that they’d have their oaths pertain to their rulers.

Too provisional. Lanterns aren’t defenders of single nations, but worlds. So bringing up the Royal Sisters and Equestria seems off.

I can’t help thinking Arimaspi would work well as a Black Lantern. He’s got a cool design and he’s dead.

Not bad! Here are my versions with a more… “Equestrian” touch:
 
 
Sinestro:  
In twilights dusk, in moonlit night,  
Evil shall cower before my might!  
To those who dare challenge my might,  
You’ll fear my power… fear’s vengeful Light!
 
Red:  
With blazing flames of raging red,  
From Tartarus depths we bring great dread,  
Through chaos, carnage, and deepest hate,  
We’ll burn you all—that is your fate!
 
Blue:  
When dark and lonely in the raging night,  
I’ll fill your hearts with smiles and light.  
When all seems lost and evil strikes,  
Look to the stars… For hope burns bright!
 
Orange:  
Through blazing days and freezing nights,  
I’ll guard what’s mine, that is my right,  
If you dare cross me you shall fall,  
What’s mine is mine, and I WANT IT ALL!!!
 
Green:  
By Celestia’s day, by Luna’s night,  
I will not flee from evil’s sight!  
To those who challenge Equestria’s might,  
Beware my power…Green Lantern’s light!
 
Star Sapphire:  
From the warm embrace of Celestia’s light,  
to the coolest breeze of Luna’s night,  
Fear not for soon all will be right,  
For love shall bloom with violet light!
 
Indigo:  
Through sorrowful day’s and stressful night’s,  
I’ll guide you all with generous light,  
To those who are gripped with great despair,  
Compassion shall guide you, for this we swear!
 
Black:  
The universe echoes with terrified cries,  
Let darkness grow as all light dies,  
My Blackest Night spreads through the skies,  
By my dark will…The dead shall rise!
 
White:  
The souls forgotten once more rise,  
To answer the universes pain-filled cries,  
Please lend your strength to our noble fight,  
Now RISE my heroes, bring forth your light!
 
All United(Sans Black):  
Should evil rise from darkness’ core,  
Face your fears,  
Protect what’s yours,  
With burning rage we’ll fight the fight,  
And fill the world with smiles and light,  
With great compassion,  
Love from your core,  
Our lights shall shine forevermore!

Here’s the versions from Takamachi Nanoha of 2814 that are different from Lantern Canon:  
The Crimson Agency  
“With blood and rage of crimson red,  
Ripped from a corpse so freshly dead!  
Together with my hellish hate,  
none other shall share in my fate!”
 
The Blue Angels  
“In fearful day, when without light…  
With my heart full, my soul ignites!  
When all seems lost, and black as night,  
look to her star, for Hope burns bright…”
 
The Order of Fate (Yellow)  
“In blackest day, in endless night…  
We turn our fears into our light!  
Let all who wish to do what’s right…  
Join HER order, make tomorrow bright!”
 
White Lanterns  
“The Brightest Day is on the rise  
The light shall soar as darkness flies.  
We guard all life from evil’s blights.  
Destiny awaits! Shine, White Knights!”

With blood and rage of crimson red,  
Ripped from a corpse so freshly dead,  
Together with our hellish hate,  
We’ll burn you all… That is your fate!
 
This power is mine, this is my light.  
Be it in bright of day, or black of night.  
I lay claim to all that falls within my sight,  
To take what I want, That is my right!
 
In blackest day, in brightest night,  
Beware your fears made into light  
Let those who try to stop what’s right,  
Burn like my power… Sinestro’s might!
 
In brightest day, in blackest night,  
No evil shall escape my sight.  
Let those who worship evil’s might,  
Beware my power: GREEN LANTERN’S LIGHT!
 
In fearful day, in raging night,  
With strong hearts full, our souls ignite,  
When all seems lost in the War of Light,  
Look to the stars, For hope burns bright!
 
Tor lorek san, bor nakka mur,  
Natromo faan tornek wot ur.  
Ter Lantern ker lo Abin Sur,  
Taan lek lek nok, Formorrow Sur!
 
For hearts long lost, and full of fright.  
For those alone in blackest night.  
Accept our ring and join our fight  
Love conquers all WITH VIOLET LIGHT!
 
The Brightest Day falls from the skies  
May the foul dead shield their dark eyes  
Burn as the white star fire descends  
Not a light that dies, but that ascends!
 
The Blackest Night falls from the skies,  
The darkness grows as all light dies,  
We crave your hearts and your demise,  
By my black hand, the dead shall rise!

I figure I’d be a Blue Lantern, but I could easily be Green instead.
 
EDIT: After a bit of research, I have concluded that I would be both.
 
It is actually possible to wield multiple Lantern Rings (As Kyle Rayner did so before becoming the first White Lantern).

I’m gonna have to go with green or blue.  
Blue: I’m very optimistic and sometimes the voice of reason within a group. It’s also one of my favorite colors.  
Green: I’m not easy to persuade and I don’t scare easy. Green also happens to be my personality color.
